CASEMENT 'WINDOW AND THE LIKE Application Ied July 7, 1930. Serial No. 465,926.

This invention relates to easement windows, doors and the like, and the objects of the invention primarily are to provide praetical and eicient weathering and to simplify the mounting` orp closures of this type in the wall of a building.

rThe foregoing and other desirable objects are attained in this invention by the novel features of construction, combinations and relations of parts as hereinafter described and broadly covered in the claims.

The drawings accompanying and forming part of the specification illustrate certain practical commercial forms of the invention and it will be understood that the structure may be modified and changed as regards these particular illustrations without departure from the true spirit an-d broad scope of the invention.

Fig. 1 is an inside view of a complete casement window having features of the invention incorporated therein; Figs.` 2, 3 and 4 are enlarged cross-sectional details as on substantially the plan-es of line 2-2, 3 3, and of Fig. 1; Fig. 5 is a similar view as on line 5 5 of Fig. 1, showing only the top and bottom portions of the window structure.

The window chosen for illustration, comprises the two vertically hinged sashes 6, 7,

. and the upper horizontally pivoted sash 8,

Fig. 1` all mounted in a `special frame 9 set* directly into the masonry or structure of the building wall. r

From Figs. 4 and 5, it will be seen that this mounting frame is of hollow channel Vform open around the outside to bon-d into the'wall, consisting in substance of side flanges 10, 11, connected about the inside of the frame by the portions 12, 13, offset by the intermediate shoulder 14, which Afaces outwardly of the window to form a contact stop for the sash liange.

At the lower end of 12 may be sloped as shown at the bottom in Fig. 5 to accord with the sill structure.

The frames 'for thesash 6, 7, 8. are shown as of standard cross-section consisting of a bar portion 15 with a wide outwardly extending iange 16 at the outside of the frame and a narrower outwardly extending sealing the frame, the tabley iiange 17 at'the inside of the frame. The

This will be particularly clear from Figs. 4 and 5, the first of which shows one of the outwardly offset hinges 19 attached to the outer flange 16, of one of the side sashes at 20, and to the portion 12 of the fixed frame at 21; the second of these views showing at the top, one of the hinges 22 for the upper swinging sash, connected like the other hinges to the outer flanges 16 of the sash at 23 and tothe outer portion 'of the fixed frame 12 at 24.

The uppercross-bar of the frame, indicated generally at 25 and shown in detail in Fig.,2, is constructed in general like the body of the frame, that is at the top with a sill portion 12a, and aftable by sto-p shoulder 14a substantially parallel portions 12?), 13b connected by shoulder 145; similarly as regards the upright intermediate bar 26 of the frame, this having the portions 120, 130, connected by the shoulders providing stops for the outer sash flanges 16.

rlhe frame and sash sections are usually of rolled, pressed, drawn, or extruded material and so in the final form have somewhat portion 13a connected and at the bottom with roughened surfaces, preventing air or weather tight vcontact at metal-to-metal oints, such as between sash lianges 16 and the frame shoulders 14.

feather tight and .dust excluding betweensash and mounting frame areprovided in the present invention byv a'weathering or stop frame set in the mounting frame and adapted to be adjusted to bring a strip of packing material into proper sealing engagement with the sash frame. y

This adjustable weathering lis shown in each instance as a lightv frame 27, `secured to the inner portion 13 of the main frame bv lscrews 28 passing through slots 29 inthe fasi i tening flanges 30 into screw seats 31 in the main frame. These adjustable weathering frames are sho-wn as having open packing channels 3Q opening outwardly of the window and carrying strips 33 of felt or other suitable packing material in position for engagement with the packingextensions 17 of the sash frame.

To provide a greater degree of resiliency, facilitate renewal of the packing, etc., the packing strips are shown as elastically and removably held in their channels by spring sheet metal clips or ianges 3a having base portions caught beneath the hea-ds of screws 28 and having inwardly angled portions 35 holding the packing strip over in the corner of the packing groove and inclined as indicated to form a dove tail or undercut groove which locks the packing in place. If desired, the packing may be secured in place by glue, cement or other securing medium.

By placing the hinges ou the inside, the sash may be made to open inwardly, in which event, it will be understood the parts will be reversed, the weathering frame carrying the packingbeing then at the outside of the window and the sash swinging inwardly away from the same.

With this invention, employ special sub frames it is not necessary to .to provide mounting connections between window frames carrying the sash and the building structure.

The present mounting frames 9 serve both assash framing and as the equivalent of what have been known as the sub frames for bonding the window structure in the building wall. Thus, the hollow window frames 9 can be sent out from the factory either with or without the weather stops in place and be set up directly in the building walls ready to receive the hinged sash as soon as building operations have progressed far enough for the hanging of the sash. If any adjustment of the weather stops is necessary to make the packing properly meet the sash, this can be readily accomplished by loosening one or more of the screws 28 and shifting the weather frames until they properly matchlthe sash,

after which they are secured in such adjusted relation in the main frame. If the packing becomes worn, the old packing may be readily removed and new packing inserted. The Vmounting anges 3() for the weather stops areshown as extending outwardly, so as to be concealed by the sash frame, but it will be understood, that, if desired, these mounting flanges might be reversed, that is extended inwardly of the window, so as to leave the adjustable fastenings 28V exposed with the sash in closed position, enabling adjustment of the stops against the sash while the sash is closed. The location of the packing material in a stationary stop frame is preferable to structures where packing inaterial is mounted in the edge of the swinging sash, because when such windows are opened, thel packing material swings out with the window and is thereby exposed to sun and weather conditions. Another important advantage in providing the weathering in a stop frame separate from the sash is that the sash frame can be made of relatively light section with the fullest area exposed to glazing. rIhe overlap for packing provided by the extension 17 is outside of the glazed portion of the frame and so does not cut down the glazed area.
